Frequently Asked Questions

What should I do if the status LED turns solid red?
A solid red status LED indicates a hardware failure or configuration error. Check the CPU LEDs to identify the specific error code provided by the module.

Can I adjust the polling rate on the INNPM01?
Yes, you can select poll rates of one, two, four, or eight polls per second using the dipswitch settings on the circuit board.

What is the most common reason for communication loss?
This often results from incorrect dipswitch configuration or loose edge connector seating. Verify that the pins are clean and the module is fully seated.

Selection Guide

When selecting an INNPM01, verify your system's current firmware version and backplane power capacity. Ensure the module's poll rate settings align with your specific process time-criticality requirements. For redundant systems, confirm your I/O expander bus configuration supports the additional communication load.
